Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server version    *
  *                  6.1 users of Java Server Faces (JSF).       *

  * PROBLEM DESCRIPTION: BeanInfoManager instances in the        *
  *                      JSF's BeanInfoManager static hashmap    *
  *                      are not removed when an application     *
  *                      is stopped which leads to               *

  * RECOMMENDATION:                                              *
  ****************************************************************
  JSF's BeanInfoManager keeps a hashmap of the classes it has
  instances of. This hashmap is not cleaned up when applications
  are stopped which causes it to hold onto references of classes
  from applications that have stopped and possibly even
  restarted. This prevents the Classloaders which loaded those
  classes from being garbage collected.
  

Problem conclusion

• Method was added to BeanInfoManager that removes all the
  entries for a given classloader. The JSF code was also updated
  to call that method when applications are stopped.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 6.1.0.21.  Please refer to the Recommended Updates
